Supersymmetry versus Integrability in two-dimensional Classical Mechanics
Supersymmetric extensions of Hamilton-Jacobi separable Liouville mechanical systems with two degrees of freedom are defined. It is shown that supersymmetry can be implemented in this type of systems in two independent ways. The structure of the constants of motion is unveiled and the entanglement between integrability and supersymmetry is explored.
متن کاملINTEGRABILITY vs. SUPERSYMMETRY
We investigate (1,0)-superconformal Toda theories based on simple Lie algebras and find that the classical integrability properties of the underlying bosonic theories do not survive. For several models based on algebras of low rank, we show explicitly that none of the conserved W-algebra generators can be generalized to the supersymmetric case. Using these results we deduce that at least one W-...
متن کاملDuality versus Supersymmetry
We study the effect of S-duality and target-space duality tranformations of N = 4, d = 4 and N = 1, d = 10 supersymmetric configurations on their Killing spinors. We find that, under reasonable assumptions, the dual configurations are also supersymmetric and that the Killing spinors transform in a simple way. There is an increasing interest in finding new classical backgrounds of string theory ...
متن کاملSupersymmetry versus Precision Experiments Revisited
We study constraints on the Minimal Supersymmetric Standard Model from electroweak experiments. We find that the light sfermions always make the fit worse than the Standard Model, while the light chargino generally make the fit slightly better through the oblique corrections. The best overall fit to the precision measurements are found when the mass of lighter chargino is about 100 GeV and the ...
متن کاملSupersymmetry versus precision experiments revisited
We study constraints on the supersymmetric standard model from the updated electroweak precision measurements — the Z-pole experiments and the W -boson mass measurements. The supersymmetric-particle contributions to the universal gauge-bosonpropagator corrections are parametrized by the three oblique parameters SZ , TZ and mW . The oblique corrections, the Zqq and Zll vertex corrections, and th...
